• Are there any wireless webcams/cameras that Windows will recognize as a capture device?

  - by Keithius

  I'd like to have a webcam in a different room from my computer, and the distance means USB is out of the question. I know there are many wireless cameras, but what I can't seem to find out is if any of them would be recognized by Windows as a capture device (just like a locally connected USB webcam). Most of the wireless cameras I can find (e.g., D-Link DCS920; Cisco-Linksys WVC54GCA, etc.) can all stream video directly from the camera itself, which is fine if you're using the camera as a "security" camera (for private use only), but not for other uses (say, sending the video to an online video streaming service, e.g., Ustream). It seems like this should be possible; after all, wireless (WiFi) printers with scanners are recognized by Windows. Are there any wireless (WiFi) cameras out there that would be recognized by Windows as a capture device in the same way as a USB webcam would? Alternatively, a camera that's not wireless (e.g., connects via Ethernet) would do the trick too - but I imagine if anyone is going to make a remote camera like this, they'd go the extra step and make it wireless, too.

• Computer causing WiFi interference?

  - by Mannimarco

  I came back from college and brought my desktop computer. Family recently switched to Verizon FIOS and got a new router because of it. Unfortunately, my connection to the new wifi network is awful, with the download speeds (tested through speedtest.net) fluctuating wildly and often dropping below 1.5 Mbps. A laptop in the same room gets 20 Mbps. I've tried a new wireless card, thinking that mine got damaged in the move home but no luck. Here's where it gets weird: if I place the laptop near the computer, the laptop's download speeds often suffer greatly. Pulling the laptop away always fixes this. So now I'm under the impression that there's something in the computer (which I built a year ago and has had 0 issues up to this point) is causing an insane amount of wireless interference. Also bizarre: the upload speeds seem unaffected by this problem. On the laptop and desktop, upload speeds are generally around 5 Mpbs. Any ideas as to what could be causing this and how to test said theories would be fantastic.

• (Mac Intel) HP PS driver prints in B&W from Adobe Reader after installing Cannon PS driver

  - by JohnB

  I have a unique problem that leaves me at a loss as to where to start troubleshooting. We have three Macs we use for graphics, two of which are PowerPC and one which is Intel. They are set up to print to an HP 5500dn, but occasionally this printer gets tied up with a massive print job, so I installed the PS driver (iR-PSv1.81MacOSX) for the Cannon C3200 Printer/copier on each of the machines. Both of the PowerPC Macs installed without issue, but the Intel Mac exhibits strange behavior: I've confirmed that while the Cannon driver is installed (whether or not the Cannon is set up for printing in print settings), the HP 5500dn will print in color from Safari, but only prints in black and white from Adobe Reader. The Cannon printer itself has not exhibited any strange behavior As soon as the Cannon driver is uninstalled, the HP 5500dn prints in color from Adobe Reader again. We run a network of Windows PCs, and the 'Mac room' mostly takes care of itself, so we don't have any experienced Mac administrators onsite. The Cannon is capable of Appletalk, but the PS driver seemed easier to work with (and Appletalk is currently disable on the Cannon. I'm not against using the Appletalk compatible drivers, but I would rather use the PS driver if at all possible - I don't want to open up the proverbial can of worms. If someone has any clues or suggestions that would help troubleshoot this problem, I would be grateful. I've already done some googling, but due to the obscure nature of this problem, I haven't been very successful. I don't like to create multiple threads on multiple sites, but I'm posting here due to Chopper3's suggestion on my post on ServerFault (http://serverfault.com/questions/135349/mac-intel-hp-ps-driver-prints-in-bw-from-adobe-reader-after-installing-cannon)

• How do I get a Wireless N PCi card to connect to a wireless G router?

  - by Andy

  I'm having some problems setting up a new wireless PCI card on a WinXP SP3 PC. I know that the router is configured correctly. It is a Linksys WRT54GL, using 802.11b/g. Security mode is WPA2 Personal with TKIP+AES encryption. I am able to connect to this fine using my laptop (first gen MacBook with a 802.11b built in card). The new PCI card is also Linksys, but it supports 802.11n. Card seems to be installed ok (Windows sees it fine, doesn't list any errors in Device Manager), however when it scans for available wireless networks it can't find my wireless network (the router is set to broadcast the SSID). I tried to enter the network SSID manually, but that didn't seem to help. I chose WPA2-PSK for network authentication. The only options for encryption are TKIP or AES - I've tried both, neither worked. I am sure that I typed in my wireless key correctly. At this point, I don't think the problem is with encryption, but something else. It almost seems like I need to switch the wireless card into g mode, but I haven't found a way to do that (if that is even possible/necessary - I thought n was fully backwards compatible with g). Also, the PC is in the same room as the router, and my laptop, so I don't think that it is an interference issue. Any ideas what I'm doing wrong? I'm running out of things to try at this point. :(

• What Wireless Router/ADSL Modem to get? N-band a must!!

  - by JJarava

  I'm looking for a Dual-N band Router OR ADSL Gateway and I'd like some recommendations. Situation: I have a 802.11b/g ADSL gateway provided by my telco, but the WIFI signal won't cover all the house (especially the living-room, so my tv-connected Mac Mini has poor to no internet access). So I'm looking to either replace the DSL modem with a N-enabled one, or to add a Router to the mix. I've had a modem+router setup for many years, and I know the advantatges (double NAT, double FW = more security) and issues (more complex to troubleshoot, two possible points of failure), so I'd rather live with a single (ADSL Gateway) device, if possible. Requirements: Dual-N Band (300 Mbs WIFI) 1 GB Ethernet ports ADSL2+ support (if it's a ADSL gateway, which would be desirable) "Best" range and speed possible Nice to have: USB port to share disks/printers on the network Media streaming I've been a long time user of Linksys, so googling around I found the WRT610N (http://www.linksysbycisco.com/US/en/products/WRT610N) for a "Pure Router" perspective, and it's one of those that Linksys styles "N++" (http://www.linksysbycisco.com/US/en/promo/Promotion-Go-Wireless?stepname=Promotion-Step-Go-Wireless-High-Performance) But I haven't been able to find similar "ADSL" gateways. I've found the WAG320N, but there is little to no info in the Linksys site (i.e., i don't know if it's Dual Band, or if it has GB ethernet) Any opinions/recommendations of other products/suggestions are more than welcome.

• Database types for customer analytics

  - by Drewdavid

  I am exploring a paid solution to start providing better embedded, dashboard-style analytics information to our website customers/account holders, but would like to also offer an in-house development option to our team. The more equipped I am with specifics (such as the subject of this question), the better the adoption rate from the team (or so I have found), regardless of the path we choose Would anyone care to summarize a couple of options for a fast and scalable database type through which we would provide the following: • Daily pageviews to a users account pages (users have between 1 and 1000 pages) • Some calculated/compounded metrics (such as conversion rate, i.e. certain page type viewed to contact form thank you page ratio) • We have about 1,500 members (will need room to grow); the number of concurrently logged in users will for the question's sake be 50 I ask because our developer has balked at providing this level of "over time" granularity (i.e. daily) due to the number of space it would take up in a MYSQL database To avoid a downvote I have asked specifically for more than one option, realizing that different people will have different solutions. I will make amendments to my question if so guided by answering parties Thank you for sharing your valued answers :)

• Will just a couple of thermal "trip" shutdowns typically damage a CPU?

  - by T.J. Crowder

  The short version If a CPU gets so hot that the system turns itself off because of a thermal trip signal just a couple of times, is it likely that the CPU will be damaged? Or does the trip do its job, turning it off before the CPU gets damaged? (This is with all default settings in the BIOS; I haven't raised any temp thresholds or overclocked anything.) The longer version I just got this Intel Atom D510-based fanless system, installed a 2.5" mobile SATA drive and two 2GB PC2-6400s, closed it up, and having checked everything was recognized in the BIOS, set about installing Ubuntu. After a couple of false starts related, I think, to the external DVD drive I was using, I got the install happily running along. About three-fourths or so of the way through the install, having been running less than an hour, the machine turned itself off. I was actually out of the room at the time, but when I came back and turned it back on, it said it had shut down due to a thermal event. I went into the BIOS and saw that (at that point, having just been turned back on after a couple of minutes off), it was running 87C. As near as I can tell from Intel's docs (PDF here), the max "junction" temperature for the CPU is 100C and it will raise a THERMTRIP signal at 125C. Yowsa. Presumably there will be some back-and-forth with the vendor on this, I'm just wondering whether letting it get that hot a couple of times is likely to end up damaging it.

• Distorted Sound

  - by BCable

  I have my laptop hooked up to my receiver for sound output. I hear a hissing/crackling background sound that is really loud and hard to just ignore (but possible). When my 360 is connected, the sound comes out perfect, so it's just with this laptop. Previously, I thought it was just my laptop and just submissively just let it slide. I just bought a brand new laptop though and it's doing the same thing. I have found out more information now that I know it's not my laptop. I have used this laptop in similar environments where it worked just fine (different speakers). I have bought a new cable to connect to my receiver and it did nothing (headphone jack to RCA). I tried different ports on the receiver (Video 1-3) and it always happens. I have discovered that the sound goes away if I unplug my laptop (so it's running on battery). Because of the last one, I tried plugging my laptop into a different outlet across the room and it's STILL doing it. Doesn't matter if I boot to Linux or Windows, yet my phone (Android G1) doesn't cause this sound using the exact same cable. Any ideas? I'm out of them! Thanks!

• Hubs/switches taking out switches?

  - by Bart Silverstrim

  Here's the issue...we have a network with a lot of Cisco switches. Someone plugged in a hub on the network, and then we started seeing "weird" behavior; errors in communication between clients and servers, or network timeouts, dropping network connections, etc. It seemed that somehow that hub (or SOHO switch) was particularly freaking out our Cisco 3700 series switches. Disconnect that hub or netgear-type SOHO switch and things settled down again. We're in the process of trying to get a centralized logging server for SNMP and management, etc., to see if we can trap errors or narrow down when someone does this sort of thing without our knowledge because things seem to work, for the most part, without issue, we just get freaky oddball incidents on particular switches that don't seem to have any explanation until we find out someone decided to take matters into their own hands to expand available ports in their room. Without getting into procedure changes or locking down ports or "in our organization they'd be fired" answers, can someone explain why adding a small switch or hub, not necessarily a SOHO router (even a dumb hub apparently caused the 3700's to freak out) sending DHCP request out, will cause issues? The boss said it's because the Cisco's are getting confused because that rogue hub/switch is bridging multiple MAC's/IP's into one port on the Cisco switches and they just choke on that, but I thought their routing tables should be able to handle multiple machines coming into the port. Anyone see that behavior before and have a clearer explanation of what's happening? I'd like to know for future troubleshooting and better understanding that just waving my hand and saying "you just can't".

• printing parallel over ethernet cable

  - by Crudler

  I have a bit of an interesting challenge :) I have a machine with a parallel printer output, i want it to be able to print instead to a printer in a different room and i know that parallel isnt great over big distances. i found this: http://www.amazon.com/over-Cat5-Extension-Cable-Adapter/dp/B002WJ9S6Y%3FSubscriptionId%3DAKIAINHICTCYYZGJWT4Q%26tag%3Dusbprintercables.net-20%26linkCode%3Dxm2%26camp%3D2025%26creative%3D165953%26creativeASIN%3DB002WJ9S6Y which will let me connect over cat5, but its usb to cat 5. my machine can only output on parallel (its not a computer) so what i was thinking of getting is a parallel(f) to usb and usb to parallel (M) for either side i.e. machine - parallel - usb - cat5 - usb - parallel -printer just seems a bit messy :) suggestions? another thing i would like to try is to get rid of the old school parallel printer and instead use a network based multi function. would this be possible? i.e. machine - parallel -usb - cat5 - ethernet print server - network printer this might be rougher because the machine cannot "know" that we are using a network printer. it can ONLY print to LPT1 Thanks!

• Recording screen-casts on another computer

  - by paleozogt

  We're trying to record the desktops of users using demo versions of our software (this is an in-house lab setup). We need to have the recording happen on a separate computer (just across the room), so that the recording software doesn't interfere with the user. Every screen recording software I've seen will only record what's happening on the computer its installed on; ie, you can't record what's happening on another computer. So it seems I need to cobble together a solution (unless anyone knows of software that will do this). Getting the video to the other computer seems easy enough. I'm using TightVNC with the DFMirage driver on the test computer. The recording computer connects to the test computer with TightVNC and then uses CamStudio to record what's happening. The real problem is how to deal with the audio. We need to record both what the user is saying (through a headset mic) as well as the sounds produced by the test computer. But VNC doesn't transmit audio. :( I'm not sure how to get both audio streams (mic and sounds) over to the recording computer. Any ideas?

• Extend RAID 1 (HP SmartArray P410i) running Linux

  - by Oliver

  I took over a fairly simple server setup with the following RAID 1 config running Ubuntu 11.10 (Kernel 3.0.0-12-server x86_64): => ctrl all show config Smart Array P410i in Slot 0 (Embedded) (sn: removed) array A (SAS, Unused Space: 1335535 MB) logicaldrive 1 (279.4 GB, RAID 1, OK) physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 1 TB, OK) physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 1 TB, OK) Initially there were two 300GB disks that got replaced by 1TB disks and I now have to extend the logical volume to use that extra space. However, when trying to do so I get the following warning: => ctrl slot=0 ld 1 modify size=max Warning: Extension may not be supported on certain operating systems. Performing extension on these operating systems can cause data to become inaccessible. See ACU documentation for details. Continue? (y/n) Is it safe to say yes or am I at risk of corrupting the file system / loosing data? Rearranging and extending the file system afterwards shouldn't be an issue as I can take the server offline and boot from a gparted live disk.

• Optimal Networking Setup for a 2-Story unit?

  - by user29336

  I am moving into a 4 bedroom two-story unit. It’s roughly 2,200 sq ft. I want absolute max throughput possible to be achieved in all focal points. We’re all in internet related industries. Between gaming and web-development latency and throughput are major factors for us. Here’s our main focal points: 1) Garage (office). downstairs 2) Each bedroom x4. upstairs 3) Living room. downstairs The fastest line we can get is Comcast 50mbdown/5up (Wideband). I am looking for the best way to achieve wireless and wired performance for our setup. Our gaming computers may be in our bedroom, and we also may bring it down to the office every now and then for “LAN” sessions. Most wireless will be happening downstairs with our laptops, but since we may do LAN sessions then hard wired latency may be important there too. My concerns: If we do only wireless there would be too much latency for gaming. I don’t know if placing one D-link DGL 4500 on the top floor would be enough; which I currently own. (http://dlink.com/us/en/home-solutions/support/product/dgl-4500-xtreme-n-gaming-router) As far as I’m aware wireless signals transfer best top down. Would this wireless router be enough on top floor and that’s it? My second strategy was a combination of wiring and wireless but I’m not sure what’s easiest way to do this? This is a place we’re renting, so I’m not sure how much leeway we have with wiring, but we’re all pretty competent... if we can’t drill through a wall we can probably “stitch” them across the edges wherever needed. Thoughts on the optimal way to do this?

• Virtual Wifi Issue Windows 7

  - by Matt

  Lately I've been trying to use my laptop as a wireless router in my room. I have it connected to my school's network through ethernet, and I want to set up wireless so that I can use Wifi on my Android phone and iPod Touch. In the past, I used Connectify, but I started having an issue where my phone would find the network, connect, attempt to get the IP, and then suddenly the network would disappear. Then it'd pop up again, and the same process would happen over and over. I decided that I'd totally uninstall Connectify, but after that, neither Virtual Router Manager nor the command prompt could create a viable network either. My phone and even my iPod now encounter the same problem. Neither can successfully connect. So evidently there is something wrong with the laptop's virtual wifi feature, and I have no idea what that could be. I've tried enabling certain services that virtual wifi supposedly relies on, but some of them don't start, namely Remote Access Connection Manager. But I also have read that these enable on their own and that if they are normally not enabled it's fine. Furthermore, I even uninstalled and reinstalled the drivers for my wireless card. Any ideas as to why my virtual wifi won't function? Anything? I really would love to get this working...

• Starting airplay from command line, to send output of 'Say' Mac OS X command to airplay

  - by Fabien

  Ok, Sunday question :) Trying to make a little joke... 1) if you open a terminal, and type "say -a ?", Mac OS X will give you the list of devices it can send spoken words to. On mine, it says: 39 AirPlay 47 Built-in Output 2) I have a Denon airplay-ready received in my living room and I'm trying to send spoken words to my wife downstairs... I can send music without any problem using iTunes so, from an infrastructure standpoint, I'm all set. 3) I want my computer to say (out of the blue) "Honey, why don't you bring me a cup of coffee". I can make it say that locally on my internal laptop speakers, but I can't seem to send that to device 39 successfully. I am suspecting that there are a few other things that need to be setup before it works, i.e. setting up airplay output to "denon", maybe opening a channel and reserving it. I don't know. Has anyone played with this? Is there a way to setup airplay from the command line? That would be awesome :)

• How could Load average numbers from 'htop' exceed 100% CPU utlization?

  - by Joe Huang

  I use 'htop' to monitor my web server. It's recently quite loaded and the Load average is showing something like this: Load average: 3.10 2.56 1.63 I searched the web about these numbers and I found an article about it: http://blog.scoutapp.com/articles/2009/07/31/understanding-load-averages In the article, it says if I have 2 CPUs, 2.0 means 100% CPU utilization. And my VPS has two CPUs, so what does 3.1 mean? How could it exceed 100% CPU utilization? And from these numbers, does it mean I should be wary about the loading now? But the performance seems totally fine, and this is a managed VPS, the hosting company has not notified me any warning about it. During day time, Load average always show these high numbers... here is another snapshot while writing. Load average: 3.03 2.77 1.97 Load average: 0.41 1.29 1.60 <---- 5 more minutes later So I am wondering how much room left for this site to grow in current configurations? What kind of proactive actions I should take in advance? I don't want to wait until the server bursts. Thanks.

• Campus VLAN Segmentation - By OS?

  - by Moduspwnens

  We've been thinking through re-arranging our network and VLAN configuration. Here's the situation. We already have our servers, VoIP phones, and printers on their own VLANs, but our problem lies with end user devices. There are just too many to lump on the same VLAN without being hammered with broadcasts! Our current segmentation strategy has them split into VLANs like this: Student iPads Staff iPads Student Macbooks Staff Macbooks Gaming devices Staff (Other) Student (Other) *Note that our network has many more iPads and MacBooks than most. Since the primary reason we're splitting them is just to put them in smaller groups, this has been working for us (for the most part). However, this required our staff to maintain access control lists (MAC addresses) of all devices belonging in these groups. It also has the unfortunate side effect of illogically grouping broadcast traffic. For example, using this setup, students on opposite ends of campus using iPads will share broadcasts, but two devices belonging to the same user (in the same room) will likely be on completely separate VLANs. I feel like there must be a better way of doing this. I've done a lot of research and I'm having trouble finding instances of this kind of segmentation being recommended. The feedback on the most relevant SO question seems to point toward VLAN segmentation by building/physical location. I feel like that makes sense because logically, at least among miscellaneous end users, broadcasts will typically be intended for nearby devices. Are there other campuses/large-scale networks out there segmenting VLANs based on end-system OS? Is this a typical configuration? Would VLAN segmentation based on physical location (or some other criteria) be more effective? EDIT: I've been told that we will soon be able to dynamically determine device OS without maintaining access lists, although I'm not sure how much that affects the answers to the questions.

• Troubleshoot dropped wireless connections

  - by Jack

  I was recently hired in the IT department of a small company (~180 users) and one of the issues that people have been complaining about is having their wi-fi connections drop during meetings. The company is using an HP ProCurve Wireless LAN with 10 APs and a controller unit located in the server room. I don't have any experience troubleshooting WLAN in a multi-AP environment, so I'm trying to at least gather information using free or cheap tools. I did a basic site survey using the free version of Ekahau HeatMapper and discovered the following in one of the conference rooms that has been a problem. The program picked up three access points (plus a bunch of others with much lower signals that were out of range): AP 1: SSID: "Unknown SSID" - Signal strength: -48 dBm - -40 dBm. Channel: 2 AP 2: SSID "CompanyMain" - Signal strength: -35 dBm or greater. Channel: 2. Security: WEP (This is the main SSID for the company's WLAN.) AP 3: SSID: "CompanyGuest" - Signal strength: -40 dBm - -35 dBm. Channel: 2. Security: WPA2 (This SSID is the company's "guest" WLAN, which was setup to allow Internet access, but prevent network access.) Is there anything that you see that is clearly a problem from the above? I'm assuming that the unknown SSID might be a big problem, and that it is an AP from a neighboring office that is causing interference. Does that seem likely? Also, regarding channel, should we try changing the channels of our APs to avoid interference with that unknown SSID? (Since everything seems to be on Channel 2?) Should our APs be on different channels? In other words, should the CompanyMain and CompanyGuest APs be on different channels? Finally, any recommendations for free/cheap tools to help me figure this out, and/or a good methodology to follow? Thanks in advance for any help. Jack

• How to choose which network connection provides the default gateway in Windows XP

  - by Cathy

  I have a laptop with an integrated NIC and a WiFi connection. Both the wired and wireless networks I am using can access the Internet. Win XP is routing all traffic through the wireless network. I want to force it to route everything through the wired network when it is available (i.e. when I am sitting at my desk with the laptop docked) and through the wireless when that is the only option (i.e. when I have undocked my laptop and carried it to a conference room, or if I am out of the office working on a different WiFi network). The wireless connection cannot be established until after I am logged into Windows, so it's always the second network to become available to the OS. I have manually overridden the metric values in the TCP/IP configurations so that the NIC has metric 10 and the WiFi has metric 20. However, Windows is still picking the WiFi adapter's address as the Default Gateway, so this isn't helping. If I manually disable and re-enable the WiFi adapter, then it will switch the default gateway to the wired network and stay that way until I shutdown Windows. How can I tell Windows XP not to replace the default gateway when the WiFi connection is first enabled?

• 5GHz vs 2.4GHz dual band router, max mbps

  - by Tallboy

  I've done a fair amount of reading before posting this but there are a few things still unclear. I just bought a Netgear WNDR3700 N600. I understand that 5GHz offers more channels, less interference because of more available channels, wont interfere with a microwave and so on, and also has a shorter range. Currently, my router is broadcasting both signals (for my iPhone on 2.4, and my computer on 5) But my question is What is the max speed of 5GHz in mbps? In the router settings, it allows me to set '300mbps', but I keep reading online that the max is 54. Is this true? I noticed when I set up the router the default for 2.4 was set to 300 and the default for 5 was set to 54, so I changed both to 300. Is this fine as well? I don't see why it wouldn't be maxed out for both by default. On the box it says max rate of 300+300 so I assume this is correct, but it's throttled down so the router isn't stressing in case you have something streaming media 24/7 and slowing the internet down too. What is the max range of 5GHz? my apt is 780 square feet, and the router is in the main living room.

• MGE UPS Cut power - What happened?

  - by JT.WK

  I have 3 x MGE Pulsar M 3000 2700w UPS units within my server room which have run perfectly up until now. On Saturday morning I noticed that one of these UPS units was no longer outputting power, the lcd displayed a message saying "load not powered" and told me to press the power button to start output. Needless to say that the servers, switches and routers is was supporting were all turned off. I tried pressing and even holding the power button, but the unit refused to start back up again. Only power cycling the unit got it back up again. I have checked the logs on the UPS, although they were useless. Nothing out of the ordinary, and no email notifications had been sent. The output level sits on about 51% and all battery checks are OK. It is now three days on and the UPS is still up and running (although I am scheduling an outage to get it out of there ASAP). Does anyone have any idea what could have gone wrong here? Is there anything else that I can check that could help?

• ISA 2000 and COD MW2 Steam

  - by twlichty

  OK, so maybe not the "proper use" of network resources, but we enjoy the odd COD game during lunch hours. When we played COD4, we had a dedicated server setup at the back of the server room. With MW2, we need to be able to connect to steam to be able to play multi-player. I've found this support article here: https://support.steampowered.com/kb%5Farticle.php?ref=8571-GLVN-8711 Which outlines all the ports I need to open. I went through and created the following rules in ISA 2000 (I'm stuck with 2000 for now). Protocol Definition: Steam Primary connection: Port 27000, UDP, Send Receive Secondary Connection: Port range 27001-27030 Send Receive Protocol Definition: Steam TCP In Primary connection: 27014, TCP, Inbound Secondary Connection: Port range: 27015-27050, Inbound Protocol Definition: Steam 4380 Primary connection: 4380, UDP, Send Receive When I start steam on my local workstation (I did add an exception to the Vista Firewall to allow steam), the steam client sits on "Updating Steam" for 5 minutes then errors out with: You must connect to the internet first. Any ideas? I assume I missed something. Thanks for your help.

• Corliss Expert Group Home Security: How to Secure Your Home without Spending Too Much?

  - by Mika Esmond

  HOME SECURITY: HOW TO SECURE YOUR HOME WITHOUT SPENDING TOO MUCH Imagine if there were no burglar or criminals who threaten the safety of our homes; we will be surprised how much savings we would have on several things we do to secure ourselves and our loved ones. We would not need fences, gates with locks, doors locks, window grills, CCTV cams, perimeter lighting, shotguns and baseball bats. The cost of maintaining these things can run up to the entire cost of building another room or, in some cases, a whole new house. The rationale for home security is the same for national security. A nation maintains an army whether it has enemies or not; so, whether burglars will come or not, we have to prepare for the eventuality. Hence, we end up spending for something we might never put into the actual use it was intended for. You buy a pistol and when a burglar breaks in you fire the gun either to scare or disable the intruder. We hope we will never have to use these things; but we still buy them for the peace of mind that comes from knowing we can secure or protect our family and home.

• Wiring my internet

  - by u8sand

  I have Verizon internet service and am currently using wifi. My router is in the basement and my desktop computer is 2 floors and on the other side of the house above it... Worst possible positioning but that's just how things worked out. My wireless currently is extremely unstable so I've decide to correct the problem by wiring my computer directly. The problem lies here: when redoing the room next to it (when the wall was open) we went ahead and wired some coaxial cable from our attic to our basement (with plenty of slack on both ends, don't ask me why we didn't go ahead and wire a CAT6 cable). The question is: Can I use the coaxial cable to bring me internet connection? Naturally the router (which needs to stay where it is) takes a coaxial cable input and has Ethernet outputs. So maybe I would have to take a ethernet cable, convert to coaxial-coaxial to my computer, convert back to ethernet. Is this even possible to convert from coaxial to ethernet? Or do I have to attempt to go ahead and fish a cat6 cable through my house. I cannot just split the signal because that would require two routers and two networks (which I don't believe would work with one cable-one ISP correct me if I'm wrong). Thanks

• Connection refused in ssh tunnel to apache forward proxy setup

  - by arkascha

  I am trying to setup a private forward proxy in a small server. I mean to use it during a conference to tunnel my internet access through an ssh tunnel to the proxy server. So I created a virtual host inside apache-2.2 running the proxy, the proxy_http and the proxy_connect module. I use this configuration: <VirtualHost localhost:8080> ServerAdmin xxxxxxxxxxxxxxxxxxxx ServerName yyyyyyyyyyyyyyyyyyyy ErrorLog /var/log/apache2/proxy-error_log CustomLog /var/log/apache2/proxy-access_log combined <IfModule mod_proxy.c> ProxyRequests On <Proxy *> # deny access to all IP addresses except localhost Order deny,allow Deny from all Allow from 127.0.0.1 </Proxy> # The following is my preference. Your mileage may vary. ProxyVia Block ## allow SSL proxy AllowCONNECT 443 </IfModule> </VirtualHost> After restarting apache I create a tunnel from client to server: #> ssh -L8080:localhost:8080 <server address> and try to access the internet through that tunnel: #> links -http-proxy localhost:8080 http://www.linux.org I would expect to see the requested page. Instead a get a "connection refused" error. In the shell holding open the ssh tunnel I get this: channel 3: open failed: connect failed: Connection refused Anyone got an idea why this connection is refused ?
